Title (EN) METHOD OF OPTIMIZING DRILLING OPERATION USING EMPIRICAL DATA
(FR) PROCÉDÉ D'OPTIMISATION D'OPÉRATION DE FORAGE À L'AIDE DE DONNÉES EMPIRIQUES
Abstract:
(EN) A method for drilling a wellbore includes: generating an optimal cluster using historical drilling data; drilling an interval of the wellbore; and while drilling the wellbore interval: generating a working cluster using data collected while drilling the wellbore interval; identifying a plurality of data points proximate to a centroid of the working cluster; selecting one of the data points that converges toward a centroid of the optimal cluster; and adjusting one or more drilling control parameters using the convergent data point.
(FR) L'invention concerne un procédé de forage d'un puits de forage qui comprend les étapes suivantes : génération d'une grappe de puits optimale à l'aide de données de forage antérieures ; forage d'un intervalle du puits de forage ; et pendant le forage de l'intervalle du puits de forage : génération d'une grappe de puits de travail à l'aide de données collectées pendant le forage de l'intervalle du puits de forage ; identification d'une pluralité de points de données à proximité d'un centroïde de la grappe de puits de travail ; sélection de l'un des points de données qui converge vers un centroïde de la grappe de puits optimale ; et réglage d'un ou plusieurs paramètres de commande de forage à l'aide du point de données convergent.
